NASA proposes 'Ice Home' design for future Mars explorers

December 30, 2016

Washington, Dec 30: The first explorers on Mars may build their homes using the ice beneath their feet to effectively protect them from the harsh martian environment and provide a safe place to call home, NASA scientists say.

iceWhen astronauts set foot on Mars, they may stay for months rather than days as they did during Apollo missions to the Moon.

The surface of Mars has extreme temperatures and the atmosphere does not provide adequate protection from high-energy radiation, NASA said.

These explorers will need shelters to effectively protect them from the harsh Martian environment and provide a safe place to call home.

According to researchers at NASA's Langley Research Centre in Virginia, the best building material for a new home on Mars may lie in an unexpected material: ice.

"Mars Ice Dome," is one of many potential concepts for sustainable habitation on the red planet in support of the agency's journey to Mars, NASA researchers said.

"After a day dedicated to identifying needs, goals and constraints we rapidly assessed many crazy, out of the box ideas and finally converged on the current Ice Home design, which provides a sound engineering solution," said Kevin Vipavetz, Langley senior systems engineer.

The "Mars Ice Home" is a large inflatable torus, a shape similar to an inner tube, that is surrounded by a shell of water ice.

The Mars Ice Home design has several advantages that make it an appealing concept, according to NASA. It is lightweight and can be transported and deployed with simple robotics, then filled with water before the crew arrives.

It incorporates materials extracted from Mars and because water in the Ice Home could potentially be converted to rocket fuel for the Mars Ascent Vehicle, the structure itself doubles as a storage tank that can be refilled for the next crew.

Another critical benefit is that water, a hydrogen-rich material, is an excellent shielding material for galactic cosmic rays – and many areas of Mars have abundant water ice just below the surface.

Galactic cosmic rays are one of the biggest risks of long stays on Mars. This high-energy radiation can pass right through the skin, damaging cells or DNA along the way that can mean an increased risk for cancer later in life or, at its worst, acute radiation sickness.

Space radiation is also a significant challenge for those designing potential Mars outposts. For example, one approach would envision habitats buried underneath the Martian surface to provide radiation shielding.

However, burying the habitats before the crews arrive would require heavy robotic equipment that would need to be transported from Earth.

Oakland, Jun 2: Facebook employees are using Twitter to register their frustration over CEO Mark Zuckerberg's decision to leave up posts by President Donald Trump that suggested protesters in Minneapolis could be shot.

While Twitter demoted and placed a warning on a tweet about the protests that read, in part, that “when the looting starts the shooting starts,” Facebook has let it stand, with Zuckerberg laying out his reasoning in a Facebook post Friday.

“I know many people are upset that we've left the President's posts up, but our position is that we should enable as much expression as possible unless it will cause imminent risk of specific harms or dangers spelled out in clear policies,” Zuckerberg wrote.

Trump's comment evoked the civil-rights era by borrowing a phrase used in 1967 by Miami's police chief to warn of an aggressive police response to unrest in black neighborhoods.

On Monday, Facebook employees staged a virtual “walkout” to protest the company's decision not to touch the Trump posts according to a report in the New York Times, which cited anonymous senior employees at Facebook.

The Times report says “dozens” of Facebook workers “took the day off by logging into Facebook's systems and requesting time off to support protesters across the country." “I work at Facebook and I am not proud of how we're showing up.

The majority of coworkers I've spoken to feel the same way. We are making our voice heard,” tweeted Jason Toff, a director of product management at Facebook who's been at the company for a year.

Toff, who has a verified Twitter account, had 131,400 “likes” and thousands of retweets of his comment. He did not immediately respond to a message seeking comment on Monday.

“I don't know what to do, but I know doing nothing is not acceptable. I'm a FB employee that completely disagrees with Mark's decision to do nothing about Trump's recent posts, which clearly incite violence. I'm not alone inside of FB.

There isn't a neutral position on racism,” tweeted another employee, design manager Jason Stirman.

Stirman did not immediately respond to a request for comment on Monday. Sara Zhang, a product designer at the company, tweeted that Facebook's “decision to not act on posts that incite violence ignores other options to keep our community safe.

The policy pigeon holes us into addressing harmful user-facing content in two ways: keep content up or take it down.” “I believe that this is a self-imposed constraint and implore leadership to revisit the solution,” she continued. Zhang declined to comment to The Associated Press.

Representatives for Facebook did not immediately respond to messages for comment.

Twitter has historically taken stronger stances than its larger rival, including a complete ban on political advertisements that the company announced last November.

That's partly because Facebook, a much larger company with a broader audience,targeted by regulators over its size and power, has more to lose. And partly because the companies' CEOs don't always see eye to eye on their role in society.

Over the weekend, Twitter changed the background and logo if its main Twitter account to black from its usual blue in support of the Black Lives Matter protesters and added a #blacklivesmatter hashtag. Facebook did the same with its own logo on its site, though without the hashtag.

Washington, May 15: A top US senator has unveiled an 18-point plan, including enhancing military ties with India, to hold the Chinese government accountable for its "lies, deception, and cover-ups" that ultimately led to the global COVID-19 pandemic.

The prominent suggestions are moving manufacturing chain from China and deepening military-strategic ties with India, Vietnam and Taiwan.

"The Chinese government maliciously covered up and enabled a global pandemic that has caused misery for so many Americans. This is the same regime that locks up its own citizens in labour camps, steals America's technology and jobs, and threatens the sovereignty of our allies,” said Senator Thom Tillis, presenting his detailed, 18-point plan on Thursday.

"This is a major wake-up call to the United States and the rest of the free world. My plan of action will hold the Chinese government accountable for lying about COVID-19; sanctioning the Chinese government while protecting America's economy, public health, and national security," he said.

The plan seeking to create a Pacific Deterrence Initiative and immediately approve the military's request for USD 20 billion in funding. It also calls for deepening military ties with regional allies and expand equipment sales to India, Taiwan and Vietnam.

Encourage Japan to rebuild its military and offer Japan and South Korea sales of offensive military equipment, it said.

"Move manufacturing back to the US from China and gradually eliminate our supply chain dependency on China. Stop China from stealing our technology and provide incentives to American companies to regain our technological advantage. Strengthen cybersecurity against Chinese hacks and sabotage," the plan stated.

"Prevent American taxpayer money from being used by the Chinese government to pay off their debt. Implement the US ban on (Chinese technology company) Huawei and coordinate with our allies to implement similar bans,” it added.

The plan seeks restitution from the Chinese government and imposition of sanctions for lying about the virus. It further said China should be sanctioned for their atrocious human rights record.

Senator Tillis' plan urges the Trump Administration to formally request the International Olympic Committee to withdraw the 2022 Winter Olympics from Beijing.

"Stop China's propaganda campaign inside the United States. Treat Chinese government-run media outlets as the propaganda proxies that they are," the plan stated.

Urging the government to investigate the Chinese government's cover-up of the spread of COVID-19, the plan also seeks to investigate America's reliance on China's supply chains and threats to public safety and national security.

"Ensure the independence of the WHO through investigations and reform. Expose and counter China's predatory debt-trap diplomacy targeting developing countries. Increase intelligence sharing on potential pandemics and lead the creation of a watchdog organization to monitor foreign governments' handling of deadly viruses," Tillis said in his suggestions.

The coronavirus, which first emerged in China's Wuhan city in December last, has killed over 3,00,000 people with 4.3 million confirmed cases across the world. More than a quarter of all confirmed COVID-19 cases are from the US.

There has been increasing pressure on the President Trump, in the last several weeks, to take action against China as lawmakers and opinion-makers feel that the COVID-19 spread across the world from Wuhan because of Chinese inaction.

Meanwhile, Senator John Barrasso, in a speech on the Senate floor on Thursday, highlighted the need to update the Foreign Intelligence Surveillance Act (FISA) legislation that was put on hold by the coronavirus pandemic.

"The virus could have been contained had it not been for the Chinese Government's unscrupulous cover-up. China knew the risk months before the rest of the world; yet Chinese communist leaders destroyed key evidence, they under-reported the number of coronavirus cases, and they misled the world about its deadly, rapid spread," he said.

Asserting that the virus should have been contained in Wuhan, he said tens and tens of thousands of Americans and hundreds of thousands of people worldwide have died as a result of China's failure.

Barrasso said the US should encourage its companies to create American and western supply chains. "That way our frontline workers have what they need in the time of crisis," he said.

"Not again, not ever will we be exclusively sourced for critical drugs from China. We should diversify supply and bring home as much of our supply chain as possible," he added.

Congressman Troy Balderson introduced bicameral legislation with Congressman Doug Collins and Senator Lindsey Graham that will hold China accountable for deceptive actions taken by its leaders that led to the spread and subsequent global pandemic.

The COVID-19 Accountability Act authorises president Donald Trump to impose sanctions on China if it fails to cooperate with a full investigation led by the US or its allies into the events that lead to the COVID-19 outbreak.

"The number of Ohioan lives needlessly claimed by this pandemic could have been significantly reduced had China taken appropriate measures to control the virus' spread and disclose its severity," said Balderson.

"The United States can't look the other way when China so recklessly compromised worldwide health and the global economy. China and its Communist Party leadership must be held accountable," he said.

Tehran, Feb 28: The coronavirus epidemic in Iran has cost 26 lives, the health ministry announced Thursday, with a vice president becoming the latest top official to be infected as the spread appeared to accelerate.

Health ministry spokesman Kianoush Jahanpour told a news conference that the tally of infections had risen to 245 with 106 more cases confirmed -- the highest number for a single day since Iran announced its first infections on February 19.

The Islamic republic has the highest death toll from the virus outside China, where COVID-19 first emerged.

Among the latest coronavirus sufferers is one of Iran's seven vice presidents, Massoumeh Ebtekar, who oversees women's affairs.

Ebtekar, a former spokeswoman for students who took 52 Americans hostage at the US embassy in Tehran in 1979, is being treated at home and members of her team have been tested, state news agency IRNA reported.

Mojtaba Zolnour, head of parliament's national security and foreign affairs committee, also contracted the virus, appearing in a video posted by Fars news agency saying he was in self-quarantine.

The cleric is a deputy for the Shiite holy city of Qom in central Iran where the country's first cases were detected.

According to media reports, among the deceased in Qom on Thursday was theologian Hadi Khroroshahi, who in 1981 was named Iran's first ambassador to the Vatican.

The announcement by Zolnour comes two days after another top official, deputy health minister Iraj Harirchi, head of the government's coronavirus task force, said he too had contracted the virus.

On Wednesday, Iranian authorities announced domestic travel restrictions for people with confirmed or suspected infections.

They also placed curbs on access to major Shiite pilgrimage sites, including the Imam Reza shrine in second city Mashhad and the Fatima Masumeh shrine in Qom.

Visitors to the shrines will be allowed to visit on condition they are provided "with hand-washing liquids, proper (health) information, masks", Health Minister Saeed Namaki said.

They must "not gather together in groups but just pray and leave", he said.

In a rare move, authorities announced the cancellation of the main Friday weekly prayers in Tehran, Qom and Mashhad as well as in the capitals of 22 of Iran's 31 provinces and other infected areas.

"All of these decisions are temporary and if the situation changes, we might intensify or ease them," Namaki said.
